INSTALLATION INSTRUCTIONS

This alarm is for conditioned* indoor installations

only and should be located in an area where it will

be readily observed by the occupants. Outdoor

installation will void the warranty!

*Conditioned living space that is temperature and

humidity controlled.

TOOLS NEEDED

DIRECT PIPE MOUNTING -

HORIZONTAL & VERTICAL PIPE

1. Choose a location on the suction side of the

radon fan (a minimum of 12 inches from fan)

in an area readily observable by building

occupants.

2. Drill a hole using a 9/16” drill bit. Clean hole of

drill debris and make sure the pipe surrounding

the hole is clean and free of dirt, oils and grease.

3. Without removing the protective lm on the

pipe mount adapter, test the t by placing the

adapter into the hole in the pipe and adjust hole

if necessary.

4. Connect one end of the silicone pipe connector

elbow to the alarm housing port located inside

the battery compartment by pushing it onto the

port barb.

5. Slide the pipe mounting bracket into the back of

the alarm housing, making note of the curvature

and how it relates to the orientation of the pipe

at the place of installation. Connect the open

end of the silicone pipe connector elbow to the

pipe mounting bracket port by pushing it onto

the port barb.

6. Peel back the protective lm on the mounting

tape and insert the assembled alarm/bracket

assembly into the drilled hole, making sure it is

level, and rmly press in place to seat mounting

tap (See ACTIVATION section for alarm activation

instructions). When attaching the pipe adapter

for the alarm, rst make sure the pipe is clean, dry

and free of any debris.

NOTE: ADAPTER MUST BE PRESSED FIRMLY AGAINST

PIPE FOR 30 SECONDS TO ENSURE THAT THE 3M TAPE

BONDS TO THE PIPE AND BRACKET SURFACES.

Alternative Pipe Adapter Mounting: Once the

selected adapter is installed (Note: make sure

that the connector elbow is NOT installed), slide

off alarm body from adapter and attach the

adapter plate using two of the four adapter plate

holes and two screws provided with the ARNALM

(a 1/16” drill bit can be used to drill pilot holes in

the pipe). NOTE: regardless of adapter orientation

(horizontal or vertical in relation to the alarm), use

the two screw holes located at 9 and 3 o’clock so

that the screws do not interfere with sliding the

ARNALM onto the adapter.

REMOTE - WALL MOUNTING

1. Mount the ARNALM Alarm within 50’ of where

the radon system piping will be monitored. Wall

surface must be clean and free of dirt, oils and

grease.

2. Using a liquid level and pencil, mark a line on

the wall surface where the edge of the ARNALM

housing will be located.

3. Mount the pipe adapter (at a minimum

distance of 12 inches from the fan) on the

suction side of the radon fan. Drill a hole using a

9/16” drill bit. Clean hole of drill debris and make

sure the pipe surrounding the hole is clean and

free of dirt, oils and grease.

4. Without removing the protective lm on the

pipe mount adapter, test the t by placing the

adapter into the hole in the pipe and adjust hole

if necessary.

5. Peel back the protective lm on the mounting

tape and insert the pipe mounting bracket onto

the radon system pipe.

6. Connect one end of the tubing (50’ max; sold

separately) to the pipe mount adapter by

pushing the tubing onto the port barb. Route the

tubing to the location where the ARNALM alarm

will be mounted, avoiding pinching or kinking the

tubing along the way.

7. Insert the tubing into the hole located at the

bottom of the alarm housing until it reaches into

the battery compartment.

8. Connect the tubing to the alarm housing by

pushing the tubing onto the port barb. Slide

the wall mounting bracket into the back of the

alarm housing.

9. Peel back the protective lm on the mounting

tape and rmly press the assembled alarm/

bracket assembly onto the wall to seat

mounting tape, making sure it is aligned with the

pencil mark previously placed on the wall.

NOTE: ARNALM uses a permanent tape that may

cause damage if removed. If you must remove

the mounted device, use a piece of dental oss or

wire held tautly between two hands. Pull back and

forth to split the tape, and release the mounted

object. (See ACTIVATION section for alarm

activation instructions)

ABOUT THE ALARM

The Radon System Alarm is a vacuum monitoring

product utilizing piezoresistive pressure sensor

(PPS) technology. This product provides audible

and visual indication when the Radon System’s

vacuum pressure has dropped below the preset

operating limit, resulting in insufcient pressure to

be effective.

FUNCTIONAL MODES

Sensing Mode (Visual Only) - Sensing light blinks

@ 60-second intervals (3 ashes).

Pre-Alarm Mode (Visual Only) - Alarm light blinks

@ 60-second intervals when low or no pressure

is sensed. Pre-alarm ends when the pressure is

restored within the selected delay duration or it

enters Alarm Mode.

Alarm Mode - After selected delay duration, buzzer

beeps and Red alarm light ashes, then no light

or beep for 60 seconds, then repeat until “Hush” is

pressed or system is serviced.

Service Mode - After 3 pre-alarm conditions occur

within the selected delay duration, buzzer beeps

and blue Service light ashes, then no light or

beeps for 60 seconds, then repeat until “Hush” is

pressed or system is serviced.

Hush Mode - Silences audible sound for 7 days but

visual remains as programmed; after 7 days goes

back to sensing mode, alarm mode (with sound)

or service mode (with sound).

Low Battery Mode - 1 “chirp” and simultaneous

ash @ 5-minute intervals.

Test Mode - Audible “beep” sounds and all lights

illuminate when “Test” button pressed.

Step 1: Press and hold “Hush” button for a

minimum of 5 seconds to start the time delay

selection mode.

Step 2: Keep “Hush” button held down until the

desired time delay appears (every 5 seconds) as

shown below:

Step 3: Stop depressing “Hush” button when

desired time delay appears as indicated by the

LEDs. Time delay selection mode will cycle in a

continual loop until the “Hush” button is no longer

depressed. Once the “Hush” button is no longer

depressed the time delay mode will no longer be

activated.

ACTIVATION

Prior to alarm activation, make sure both ends of

the silicone pipe connector are connected and

the radon fan is running. Remove the battery

isolator installed for shipping from the positive

pole end of the battery. The battery may have

been shipped separate from the alarm box and

in that case, the battery must be installed to

activate. Ensure battery is properly seated. Alarm

is now powered on and will begin the activation

sequence automatically.

Isolator

CALIBRATION

The ARNALM self-calibrates automatically upon

installation of the battery. After the alarm is

powered on, the system will run a 20-second

initialization to measure baseline system

operating pressure. The green sensing LED will

ash during this time. A single beep of the buzzer

will indicate the initialization is complete and the

alarm is now active. No additional calibration is

necessary.

AUDIBLE ALARM DELAY SELECTION

The ARNALM comes equipped with three optional

audible & service alarm delays. To select the

desired alarm delay duration complete the
